L.F. RADIO-DATA: Specification of BBC phase-modulated transmissions on long-wave
Abstract
The British Broadcasting Corporation long-wave a.m. transmitter network carries a low bit-rate data signal, in addition to the normal program signal modulation. The data signal is conveyed by phase-modulation of the carrier, the signal parameters being chosen so that there is no disturbance to reception on existing domestic receivers. The data signal is described. Details of both the data signal message structure and the modulation parameters are given.
